Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that the pattern repeats uniformly throughout the circumference of the tire;

FIG. 2 is a side view thereof; the opposite side view being identical thereto;

FIG. 3 is a front elevational view thereof; and,

FIG. 4 is an enlarged fragmentary front elevational view thereof.

The side views of the inner and outer sides of the tire are the same, i.e., the tire tread is symmetrical. The broken lines defining the sidewall, inner bead, shoulder tread, and the peripheral boundary between the tire tread and the sidewall illustrate environmental subject matter only and form no part of the claimed design. 

CLAIM The ornamental design for a tire tread, as shown and described.
